Application ined aprii s, i925. sei-iai No. 20,534.

This Vinvention relates to a loom 'for Weavingn tufted fabrics, such asAxniinster rugs, and relates more pt icularly to an improved means for,supplyi yarn to the tubes or presenters that introf'luce the tuftsbetween the warp threads.

The piin'iary aim of` this invention is to provide'a pile fabiic'looinin which the tufting yarn is drawn from a source of supply mountedindependently of the tube frames.

It is a further object of this invention to provide a loom of thischaracter Which will eliminate streaks in the Woven fabric. 1

it is a still further object of this .invention to provide a loomwherein the number of tube frames used is very greatly reduced, and alsoto provide means for automatically reversing the tube frame carryingchain.

Anotherobject is to provide a loom apted to be used with the clamp tubeframe described and claimed in my copending application, Serial No.20,533, filed concurrently herewith, and to provide means on the loom tocooperatewith the releasable clamp' on said tube frame.'

A still further object isv to provide iniy proved means forautomatically tensioning the yarn.

Further ob3ects and advantages of my invention will be apparent from thefollowing' description, talren in conjiiiictionivith the acthisspecification, andv in vehicln` Figure l is a d'iagranin'iatic sideelevation of an Anninster loom embodying;b my 'inve partsbeing omittedfor the salie of clai'i Figure 2 a front elevation on au enlarged scaleof the rlovi'ernio;i,t tube'V frame of lia'iuel and its associatedparts, the other coinpanying 'drfiWinOs which form a parrot tube framesbeing' omitted, and partsv being broken away; and

Referring; more particularly to the draW-' ings, in which likeyreference characters denote like parts throughout the several v,viewsthereof, l represents the framerof aii Aie,

minster loom of standard type,-havi ng a binder Warp beam ll and astaffer 4'Warp beam l2. Thebinder Warp threads fronithe beaut-l ll passover the Whip roll 13, and the stutter "arp threads pass over VWhip rolll,

both sets ofi'varp threads passing throughy lieddles (not shown), whicharek adapted tol form a suitable shed upon manipulation of the sheddingmechanism. The various Warp threads, together `with the selvaggethreads4 (not shoiifn), passforivard through reed l5 eri 1f mounted onlay 16,'and are united at the.

fell of the fabric. The usual needle mechaiiisiii (not shown)A ismounted on vone side of the loom, `and serves to insert the filling intothe sheds asis customary in this type of.

loom. The Woven fabric passes around spike roll 17 and over stripperroll 18, Vand thence d'ovvn to a suitable Wind-u'p`- mechanism (not-7shown). y'The lay 16 `ispivotally n'iounted on a shaft 19, andisactuated by connectors 2O throughsuitablemechanism (not shown),iiicluding cams on the main cam shaft 2l.

The tuftj'yarns'ror pile forming threads are inserted between thestuiferand binder Warp threads by means of tube yframes 2:2 of novelvconstruction, which are fully disclosed and.-

cla'imed in my copending application, Serial No,`20,583, vfiledconcurrently herewith, and i which are described in greater detailbelow.l

The tube framesQZare niountedfin the usual manner on continuousforvendless cari mounted on shaft to prevent unintentional ii'ioveinentorslippingl 4of the chains23 due Vto the unbalanced Weight of thetubeframes.`

1tion brake is'not. shown in the drawings asv its construction andV usevare Well `known iii thefart. i f y .n y rllie lowermost tube frame 22may be, re

moved, fromthe carrying,` :chains '23 for the insertion of tufts in` thefabric, by clutches Q6 pivoted at 2,7' to transferfor. clutch arms 28.vThe clutch arinsfQS arefmovable aboutl vert-ical studs 29 and ahorizontalv dip shaft i i 30 in the usual manner, so that the tube framemay be released from the carryingv v l t These moire-f.A

chains, presented at the fell' of the' fabric, and returnedto thechains. ments are controlled by suitable mechanism operated by camsonthe cani shaftQl. 'lie Y tube frame is given a wiping movement in ithe Warp, which aid/ s iiiaterially in insert-V ingthe tufts, byineansofconnectors Blipiv- 'oted to the clutches Q6." Each connectorl3l' is operated by a bell craiillever 32 Vwhich is to the loom frame10.

in turn moved by a connector 33 operatively connected to a suitable camon the cam Ythey are well known to persons skilled in the art and formno part of the present invention, further description is deemedunnecessary.

Those parts which are more intimately associated with the presentinvention will now be described.

The endless chains 23 are also supported upon s'n'ockets 41, 42, 43 and44 mounted upon a suitable super-.structure secured The arrangementshown in Figure 1 is employed in order that twovof the passes orsections of the chain may be substantially vertical and "moving in thesame direction. These sections are marked 46 and 47, and Atheir functionwill be stated below.

The shaft 25 may be rotated to feed the chains 23 by means of a tubeframe chain feeding` mechanism of known type, such as vthat disclosed inthe patent to Clark, No.

1,472,459, dated Oct. 36, 1923. This mechanism comprises a pair ofratchet wheels (not shown) iixed to the shaft 25 and having ratchetteeth facing in opposed directions. A pair of feed pawls (not shown) areregularly moved angularly about the axis of the shaft 25 by links 51which connect the feed pawlsupports with a bell crank 53 actuated by acam 5401.1 the loom cam shaft 21. A guard plate or shield 55 is mountedon a kfixed pivot 56 and engages studs in the pawls, The guard plate ismovable upward or downward, and in cach eXtreme 'posit-ion f it permitsone of the pawls to become operative and holds the other inoperative. InFigure' 1 the guard plate is shown in its downwardposition, in whichposition it per mits the chains 23 to be fed in the direction of thearrow A, Figure 1. f

` The guard plate 55 is connected by a link to a reversing;v arm 58pivoted to a bracket 59 secured to the superstructure 45. A reversingVchain 60 passes over sprockets 61 rotatably mounted on studs secured toa lower longitudinal member of the frame 45.

YThe chain 60 carries a plurality of cams whichV are adapted to engage aroller 64 mounted on the reversingr arm 53. The arm 53 willthus beraised when the roller 64 is on top of one of the cams 63, and willtherefore reverse the direction of feed of the chains. 23.

ri`he chain 66 is intermittently fed in the direction of the arrow B ofFigure 1 by means of a ratchet 65 and pawl' 66. The pawl 66 is moved byan arm 67 connected to the bell crank 53 by a link 68. It will be notedthat the construction is such that the chain 60 is moved one link on theforJ ward throw of the bell crank 53 and the chains 23 are moved onelink on the rearward throw of the same. These chains 66 and 23 are movedalternately in this manner in order that the reversing arm 58 andconsequently the gnardplate 55 may be stationfifhe beams are marked I,H, 1H', and IV to correspond with the tube frames which they supply. Theyarns from the beams I and il pass around the rear side of the shaft 25to their respective tube frames, and the yarns from beams HI and IV passaround the forward side of the shaft. All of the yarn is disposedbetween the sprockets the shaft 25 being` clear between these sprockets,thereby avoiding' interference withy the various moving parts o f theloom,

as is clearly shownin Figure 2.

lt is evident that when a tube frame is removed from the chains 23 bythe clutches 26 and presented at the fell of the fabric for the tufting'operation, considerable yarn must be drawn from the supply beam. Thenwhen the tubeiframe is replaced on tue carrying chaiiis, the yarn wouldbe left slack. To take up this slackness i employ novel yarn tensionersor eveners 70. one'acting on the yarn passing' from each supply beam toits tube frame. lheseieveners are denoted 17, I1. lll. and IV, tocorrespond with the lettering` of the beams and tube frames with whichtheycooperate.

Each evener 70 comprises a pair of bars 71 arranged in thesameho'rizontal plane at opposite sides of the loom, the extremities ofeach bar 71 being.y secured to the vertical passes 46 and 47 of thechain 23 adjacent its side of the loom. A member 72 is pivoted to eachbar 71. and may have a straight portion 7 3 extending' forward yfrom thepivot and a. hooksshaped portion 74 'extending rearwardly therefrom. Arod 75 connects the free ends of the hooks 74. Two yarn'v leo i Lw

mounted in their' supports. The yarn is arranged so as to pass over therods 76 and "7 and below the rod 7 5. The free end. of the arm 73 ofeach member 7 2 is connected to one end of the corresponding tube frameby means of a chain 7 8. The lower end of this chain is preferablyreplaced by a softwire cable, asv this portion mustV at times bendvaround and bear against the shaft 25. y

' The member 7 2 of evener I is shown in full lines in the positionwhich it assumes when the tube frame I is in place on the carryingchains 23, and in dotted lines in the position it occupies rwhen thetube frame I is presented at the fell of the fabric lby the clutch arms26. `It is apparent that when the tube frame is lowered by the clutcharms,

thechaiii 78 will exert a pull on the member 72 which will raise the rodT5, thereby reylieving the tension on the yarn supplied to the tubeframe and releasing sumcient slack to take care of the movement ofthe'tube frame. Similarly, when the tube frame is replaced on thecarrying chains the slack thus produced will be taken up by the low'-VThe movement of the n ering of the rod 75. member T2 in the returndirection may be assured by using springs 79. or any other equivalentarrangement may be employed.

kBy securing the eveners to the vertical passes 46 and 47 of the chains23, the even-k ers are lowered or raised horizontally when the chain isfed in either direction,v and consequently the relative positions ofeachevenei' and its corresponding tube frame remain .y

claimed in my copeiiding application re-k ferred to above. This tubeframe vis provided With a releasable clamp adapted to grip the yarn andprevent it from being pulled out of the tubes, the clamp being re-Vleased by a cooperating part on the loom at the proper time to permitrelative movement of the yarn and the tube frame'. y

AThe details of the construction of the tube frame 22 are shown quiteclearly in Figures f 2 and 3, and for a further'exposition reference, ismade to my above'mentioned copending application. Y

8O having tubes 81,- end brackets V82, ears 83 andvspring hooks 84vsecured thereto. tube frame is detachably mounted onV .the

f chains 23 by means ofthe ears 83 and spring ofsliaft 25.

The tube frame as shown comprises a. bar

The;

hooks l8st in the usual y manner. `The end brackets 82 carry betweenthem a fixedshaft 85and a rotatable shaft 186. The bar-shaped yarnclamps 87 are secured to arms 88 rotat-` ably mounted on the fired shaft85, and are heldagainst the bar 80 so. as to clamp the yarn by the pressure ofthe coil springs 89, i

one end ofeach of which is securedto fixed shaft 85 While the other endbears upon one of the arms 88. Dogs 9G are iXed to the rotatable shaft86 and engage the arms 88. Triggers 91 are alsosecured to the rotatableshaft 86, and are adapted to be engaged by mechanism on the loom torotate the shaft A 88. Upon such movement of the sli-aft. 88, the dogswill force tlie arms 8S outwardly against the action of `the vspi-.ings89, thereby releasing the clamps 8T and periiiittiug relative movementof the tube frame and the yarn. rIlie tube frame is shown in Figures land 2 with the clamp closed, and in `Figure 8 with it open. l

`is above stated, mechanism is provided ou `the loom to engage thetriggers-g9l and release the clamps 87 at suitable times.l Thismechanism comprises two bell cranks 92.. each pivoted to av bracket 93secured to the' breast plate of the loom, one of tliebrackets y 93 beingpositioned near-each side of the loom below one end of the tube trame.Each ti l.)

bell cra-nk 92carries a pin 94 at its upperV endwhicliy is adapted toengage a trigger 9L of t-he tube frame when the parts are 'in theposition shown in Figure 3. The other end of the bell crank isconnectedby a link-'95 to a lever 96 pivoted to a bracket 97 securedl tothe loom frame l0. The'lever 96 carries a roller 98 which engages a cam99'on the cam shaft 2l. y f y Each ofv the tube frames is provided witha sheet metal guard 100, which is securedto the eind brackets 82 of thetube frame, and.

as is clearly shown in Figure 3, prevents the' yarn from catching on theparts mounted on the shafts 85 andV 86. These 'guards kare pio ieufidedat each end with 'a projecting tongue 101, to which the chains i8kconnecting the tube trame with the corresponding evene-r 70 may besecured. These.to'itgu'esV lOl may be bent to the. right as shown in'Figure 3 forv tube frames I and II, and to the left foi-tube framesIIIand IV. The purpose of this is to hold the chains 7 8 as far aspossible clear The operation ofvmy improved loom` will be described inso Vfar as it differs from that ofL an Airminster loom of the usualtype. Starting fromy the position of the parts shown in Figure' l, tlieAfirst half :rotation ofthe-cam shaft '2l will move the'bellcraiik 53from the extreme rearward position in which it is there shown toitslextreine forward position.V VDuringlthis movement, the f.-

-pawl 66L and ratchet 65 will fadvancethe cliainp'one linkiii'thefdirection ofthe u i u i such a direction to slide over theirrespective ratchets without engaging the same. The chains 23 haveconsequently remained stationary.

TWhile the chains have thus been sta* tionary, the tube frame I has not.The clutch arms .28 remove the tube frame I from the ca rrying chains23, irescnt it at the fell ofitheffabric for the tufting operation, andreplace it on the chains during this halfrevolution of the cam' shaft.The weaving and tufting operations are performed in usual manner, andwill therefore not be scribed herein.

The clamps 87 on the tube frame hold the varn securely to the tube framewhile the latter is being lowered and the tufts in sorted in the fabric.Vhen the tufts have been con'iiiletely formed and are-held firmly inplace by the reed IG beating up against the filling, the bellfcranks 92are actuated by their cams to force the pins Se against the triggers 91,thereby releasing the yarn clamps 8'?. The tube frame is then raise'Lthrough a slight distance by the clutch arms while the lower ends of theyarn are securely held in the fabric, thus causing relative y movementof the yarn and the tube frame.

The pins 94: next release the triggers 91, thereby reclamping'the yarn,and the shears 34 and 35 then come together and sever the yarn, leavingyarn ends projecting below the tubes which are long enough to formanother row of tufts. The clutch rarms'QS continue their upward movementand replace .the tube frame I on the chain.

IVhen the tube frame is lowered, the chains 78 secured thereto will movethe members 72 of the eveners TO in the manner above describefh'amlthereby release enough slack to enable `the tube frame to be readilylowered. .During this lowering operation yarn will be drawn from thesupply beam to compensate for that cut off during theV previous tuftingoperation in which that tube frame took part, the clamps .S7 holding`the yarn for this il'uirpose. frame is replaced on chains 23.* themembers 72 will be returned to their original position by the springs'),and the slackjtaken up.

The second half-revolution of the cam shaft will cause the bell crank 58to move back again to the position shown in Figure l. During thismovement the chains 23will be ladvanced one link in a. directionopposite to that ofthe arrow A. The tube frame IIv willV thus be broughtinto the voperative or rlhe guardplate 55 is raised by theV Then thetube' vertical position. At the Sametime the pawl 66 will travelbackwards one tooth over the ratchet G5. The chain 60 thus rei'nainsstationary during this operation.A

The third halferevolution causesa repetition of the movements describedunderthe first -half-revolution, the tube frame II merely beingsubstituted for the tube frame I, and the second cam 63 being` broughtunder the roller 454-. The fourth half-revolution of the cam shaftbrings the tube frame III yinto vertical position,y and the `fifthbrings the third cam G3 under the roller. The sixth brings tube frame IVinto vertical position, and during the seventh tufts are formed fromthis tube frame. The movement of the chain 60 which takes place duringthe seventh half-revolution does not bring an other cam under roller 64,but allows the latter to drop down upon the chain, thereby lowering theguard plate 55 yand reversing the direction of feed of the chains 28.The

eighth half-revolution therefore brings the tube frame III back intooperative position.

By thusr arranging the cams 63 on the chain 60 in groups of threefollowed by three empty links. as shown, the tube frames will bepresented in the regular sequence 1 2- 3-4--3-2-l, etc. Of course, ifthe number of tube frames to be used is changed, the number of links inthe chain 60 and the numlier and arrangement of the cams 68 must bealtered to suit. In the embodiment shown, the chain 60 should have anumber of links equal to some multiple of siX, since the chain 6() ismoved six Alinks to complete an entire cycle. The cams 68 may beconstructed so as to overlap, in order that the roller 64 will not dropdown in passing from one cam to its neighbor.

t will be obvious that my invention presents. many advantages over theusual type of Axminster loom. For example, the num-V -this means theproduction of streaks in the woven fabric may be avoided. Variationsl inthe color of the ditferent'skeins of yarns sometimes occurLand if everytuft in each longitudinal rowA is inad-e from the same piece of yarinaswould be the case Where only one tube frame is employed, a variation inthe colorl of this piece of yarn will cause a streak in the -linishedfabric. lVhere four tube. frames are used, only every fourth tuft willbe made from the off-color skein, and` consequentlyl the slightvariation in Vshade will pass entirely unnoticed. A more uniform'blending of color is therefore achieved, andthe face ofthe carpetappears perfectly uniform and evenin color. f
